Maintenance and Adjustment
Coolant Level Adjustment
Coolant Expansion Tank Cap
Allow the engine to cool.
Remove the cap from the expansion tank,
located below the left hand cockpit infill
panel, and add coolant mixture through the
filler opening until the level reaches the MAX
mark. Refit the cap.
Note:
• It is not necessary to remove the
left hand cockpit infill panel in
order to remove the coolant
expansion tank cap.
• If the coolant level is being
checked because the coolant has
overheated, also check the level in
the radiator and top up if
necessary.
• In an emergency, distilled water
can be added to the cooling
system. However, the coolant
must then be drained and
replenished with HD4X
Hybrid OAT coolant as soon as
possible.
Coolant Change
Have the coolant changed by an authorised
Triumph dealer in accordance with scheduled
maintenance requirements.
Warning
Do not remove the expansion tank or
radiator pressure cap when the engine is
hot. When the engine is hot, the coolant
inside the radiator will be hot and also
under pressure. Contact with this hot,
pressurised coolant will cause scalds and
skin damage.

Caution
If hard water is used in the cooling system,
it will cause scale accumulation in the
engine and radiator and considerably
reduces the efficiency of the cooling
system. Reduced cooling system efficiency
may cause the engine to overheat and
suffer severe damage.
